- T1649
Description
This correlation rule focuses on detecting potential threats associated with MITRE ATT&CK T1649 (Steal or Forge Authentication Certificates). The rule is designed to identify instances where 5 or more analytics related to Windows Certificate Services analytic story that are triggered within a specified time frame, which may indicate a potential attack in progress. By aggregating these analytics, security teams can swiftly respond to and investigate any suspicious activities, enhancing their ability to protect critical assets and prevent unauthorized access to sensitive information.
